Hi,

Most of the glasspacks that I've looked at have a couple things working 
against them. First - the dimples usually extend into the gas path. That 
means restriction. Second, most of them "neck down" internally restricting 
the air flow.

"Good" turbo mufflers don't do this, so they flow better.

Glasspacks were "the balls" back in the day because they were cheap and 
they met the min. requirement of a muffler. The current turbo-style 
mufflers flow great and are pretty inexpensive (figure $40 to $60 for 
name-brand mufflers, up to 20% less for "house brands" (like summit 
racing). In our case, it's worth spending a bit more to get the quality 
that some name-brand pieces offer. If you search around, you can even find 
cheap turbo mufflers in stainless so they won't rust out. How kool is 
that?
